Umuringa
Kumenyekanisha ibicuruzwa
Urupapuro rw'umuringa rushingiye ku muringa wa electrolytike, zinc na tronc nk'ibikoresho fatizo byayo, binyuze mu gutunganya ukoresheje ingot, kuzunguruka bishyushye, kuzunguruka imbeho, kuvura ubushyuhe, gusukura hejuru, gukata, kurangiza, hanyuma ugapakira. Ibikoresho bitunganya imikorere, plastike, imiterere yubukanishi, kurwanya ruswa, imikorere hamwe namabati meza. Yakoreshejwe cyane mumashanyarazi, amamodoka, itumanaho, ibyuma, imitako nizindi nganda
